What is the single side of a magnet?

One side magnet is a magnet with one side magnetic and the other side is weak. The method is to wrap the two side magnets with a specially treated galvanized iron sheet, so that the magnetic properties of the wrapped side will be shielded, the magnetic force is refracted to the other side, and the other side will be enhanced. If some occasions only need one magnetic, the other side such as magnetic will cause damage or interference; in some cases, such as the magnet on the packaging box only need a magnetic, the other side can not, there is no magnetic, so the use of a single magnetic will greatly reduce the cost and save magnetic material.










The magnetic refraction of a single-sided magnet is like the refraction of a satellite cooker to a signal or the refraction of a flashlight lamp to the light. Its refraction effect is mainly determined by the following three aspects:










1. materials: material selection and thickness, and the spacing between magnet and material is closely related. Pure iron is easy to leak magnetism. After special treatment, refraction will be enhanced. However, 100% shielding materials have not been studied yet, but the materials made by different manufacturers are different.




2. angle: according to the principle of refraction, the arc material has the best effect and the right angle material has larger refractive loss.




3. space: the magnetic line of force is like a cell phone signal in the air. It needs space to refract it. If the flashlight lamp pot is completely wrapped on the bulb, the effect will not be good because there is a large amount of light refraction and loss.




How to make use of the above principles, the effect of magnetic enhancement is the best, is the best problem between many parameters, many manufacturers are also doing experiments repeatedly, such as the ideal result of Xi'an Guotai single side magnetic treatment is enhanced 50%. This will greatly reduce the production cost and save magnetic materials in the fields of package boxes, bags and so on.
